I have a 2004 Malibu LSV and this is the first winter we have owned the boat. I know I have all the water out of the manifolds and block. I am wondering if I need to do anything with the ballast tanks. Fly high sacs have been installed in the rear lockers and I have taken those out but I am wondering about the hard tanks under floor in the middle and front of the boat. Any input is much appreciated. Thanks guys.
